功能介绍 Function introduction

进口电动偏心半球阀(调节型，切断型）采用板簧加载的可动阀座结构，阀座与球体不会产生卡阻或脱离等问题，密封可靠，使用寿命长。电动偏心半球阀V型切口的球芯与金属阀座之间具有剪切作用，特别适用于含纤维、微小固体颗粒及料浆等介质 retz The imported electric eccentric hemispherical valve (regulating type, cut-off type) adopts the moveable valve seat structure loaded with leaf spring. The valve seat and the ball will not be stuck or separated, and the sealing is reliable and the service life is long. There is a shearing action between the ball core of the V-notch of the electric eccentric hemisphere valve and the metal valve seat, which is especially suitable for media containing fiber, small solid particles and slurry

设计特色 Design features

1、解决了工业生产中的浆状、混流液体、灰尘等介质在管道输送中沉淀、易结垢、阻塞，使阀门关不严等问题 Solved the problems of slurry, mixed flow liquid, dust and other media in industrial production, such as sedimentation, scaling and blocking in pipeline transportation, and making the valve not closed tightly

2、开关轻便，开启时球与壳体脱离，无任何接触，启动扭矩小，转动灵活。关闭时，半球与阀座的挤切作用能除去密封面上的污物，使阀门顺利启闭，安全系数高，密封性能好 The switch is light, the ball is separated from the shell during opening without any contact, the starting torque is small, and the rotation is flexible. When the valve is closed, the squeezing and cutting action of the hemisphere and the valve seat can remove the dirt on the sealing surface, so that the valve can be opened and closed smoothly, with high safety factor and good sealing performance

3、密封面的偏心结构，使球面能自动补偿磨损，能保持阀门的密封，使用寿命长 The eccentric structure of the sealing surface enables the spherical surface to automatically compensate for wear, maintain the sealing of the valve, and have a long service life

4、耐磨硬密封偏心半球阀，它的密封副材料是特殊的，密封面要经过特殊耐磨处理。处理后表面硬度可达到HRC65-72度，故阀门的耐磨性能特别好 Wear-resistant hard seal eccentric hemisphere valve, its sealing pair material is special, and the sealing surface shall undergo special wear-resistant treatment. The surface hardness after treatment can reach HRC65-72 degrees, so the wear resistance of the valve is particularly good
